Henoch-Schonlein purpura(HSP) is one of the most common blood capillary allergic disorder in children, and its pathogenesis has not been well explained. The studies show that the main mechanism of HSP is the abnormality of humoral immunity, and the role of IgA is emphaszed. Meanwhile, many agents such as changes in T cell function,participation of cytokine and mediators of intlammation, suscepti-bility gene and other factors also play an important role in the incidence of HSP. The pathogenesis of HSP can be better understood through extensive analysis of the immunology factors,genetic factors,and so on.

This paper introduces the design and implementation of Bluetooth wireless management and monitoring system. Combined with hospital information system, this system replaces the current monitoring system in hospital, and thus the efficiency of hospital can be improved.

Objective To construct expression vectors that Renilla reniformis (Rluc) fused with neurotensin type 1 receptor (NTSR1),and to investigate the interaction between NTSR1 and other receptors,as well as intercellular signal transduction mechanism mediated by neurotensinl-R.Methods The human NTSR1 gene was amplified by PCR using the plasmid pcDNA3.1-hNTSR1 as template.The PCR product was digested,ligased with the plasmid pRluc and then be transformed into the competent cell Top10.The construct was identified by DNA sequencing.The recombinant plasmid was transiently transfected into human embryonic kidney 293 ( HEK293 )cells,and the expression of pRluc-hNTSR1-pcDNA3.1 was detected by confocal microscopy and Western blot.Results The fragment of 1257 bp was amplified by PCR,and the DNA sequences were identical with the gene in GenBank ( NM_002531 ).Western blot showed a band about 90kDa.Confocal microscopy showed that NTSR1 was expressed on the plasma membrane.Conclusion The pRluc-hNTSR1-pcDNA3.1 eukaryotic expression vector is successfully constructed,and the expression vector can be used to investigate the interaction between NTSR1 and other receptors,as well as intercellular signal transduction mechanism mediated by neurotensinl-R,which will provide new target for drug development.

Objective To investigate MRI examination methods and imaging manifestations of primary ureteral carcinoma, and to evaluate its clinical values when comparing with other diagnostic imaging facilities. Methods Eighty-seven cases of primary ureteral carcinoma who were operated within recent 8 years came into the study, among which, 35 cases had MRI examinations. For MRI examination, coronal heavy T2WI (water imaging) was performed to show the dilated ureter, then axial T2WI and T1WI were scanned at the obstruction level. 11 cases underwent additional Gd-DTPA dynamic contrast enhanced scans. The original pre-operative diagnostic reports of various imaging facilities were analyzed comparing with the results of operation and pathology. Results MRI showed ureteral dilatation in 33 of 35 cases, no abnormal appearance in 1 case, and only primary kidney atrophy post renal transplantation in 1 case. Among the 33 cases with ureteral obstruction, soft mass at the obstruction level was detected on axial scans in 32 cases. The lesions showed gradual and homogeneous mild to moderate enhancement on contrast MRI. The overall employment rate of imaging facilities was as follows: ultrasound (94. 3% ) , IVU (59. 8% ) , CT (52. 9% ) , MRI (40. 2% ) , and RUP (35. 6% ). The accurate diagnostic rate was as follows: MRI (91. 4% ) , RUP (80. 6% ) , CT (63. 0% ) , ultrasound (47. 6% ) , and IVU (11. 5% ). Conclusion Combination of MR water imaging and conventional sequences can demonstrate most primary ureteral carcinoma lesions and has a highest diagnostic accuracy among the current diagnostic imaging facilities. It should be taken as the first diagnostic imaging method of choice when primary ureteral carcinoma is suspected after ultrasound screening.

Objective To investigate the prognostic value of modified Glasgow prognostic score(mGPS)in patients with gastric cancer.Methods The clinical data of 600 patients with gastric cancerwho underwent surgical treatment were retrospectively reviewed.These patients were divided into themGPS0 group,mGPS1 group,and mGPS2 group according to the standard of mGPS.Postoperative survivals and risk factors that may affect patient's prognosis were analyzed among the three groups.Results There were 46 (7.7%)cases,33 (5.5%)cases and 521 (86.8%)cases in the mGPS0,mGPS1 andmGPS2 group,respectively.Except for gender(P =0.203),age,BMI,CEA,CA199,CRP,Alb,TNM stageand mGPS affected the over all survivals and there were significant differences among the groups(P <0.01).Gender,age,BMI,CEA,CA199 and TNM stage affected the mGPS and there were significantdifferences among the groups(P <0.01).Multivariate analysis identified that age(OR,1.319,95% CI1.068,1.629,P <0.01),TNMstage(OR,2.909,95% CI 2.616,3.234,P <0.01)and mGPS(OR,1.845,95% CI 1.184,2.875,P =0.007)were correlated with the postoperative death rate and they wererisk factors of poor postoperative prognosis(P <0.01).Conclusion mGPS can be used as an early,simple and effective prognostic predictor of postoperative survival for patients with gastric cancer.

Every stage of tumor initiation and development closely relates to immune regulation as tumor cells tend to evade attacks from immune system by employing the programmed death 1 (PD-1)/ programmed death-ligand 1 (PD-L1) interaction.Therefore,targeting the PD-1/PD-L1 pathway has become an attractive approach for cancer immunotherapy.Radiotherapy has long been considered a local tumor treatment modality and it is immune-inhibitory.However,accumulated evidence has shown that radiotherapy might enhance immune function by eliminating the tumor mass and has become a systemic tumor treatment modality.These observations indicate a strong rationale that the radiotherapy and anti-PD1 and anti-PD-L1 immunotherapy may work synergistically to provide a powerful anti-tumor effect.This review discusses current progresses,challenges and perspectives of this novel combination treatment modality.
